Hi Mark,
Seems we raced last night. I pushed the fix about 5 minutes after
you sent this :)
https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio.git/commit/?h=togreg&id=a1e5b99bc7c6b6a1c3c3b79a8fba1dc16ea160fa
Sasha gave a heads up that this was coming yesterday.
There are a couple more i3c related fixes but the more significant of those
issues probably doesn't turn up in next builds because the real fix
is in the i3c tree and I'm just papering over being unable to cleanly
pull that into IIO tree.
